BRIDGTON – Shively Labs announces that its Model 2914 filter was selected as part of the Towercast HD Radio demonstration project in Paris, France.

TowerCast, France’s first privately held tower company, teamed with parent company NRJ Group and SIRTI to begin broadcasting HD Radio on a test license granted for 88.2 MHz.

Shively Labs provided its Model 2914-4 four cavity low power bandpass filter as part of the equipment package for the demonstration system. The filter is tuned to suppress out-of-band emissions that may cause interference to broadcast signals on neighboring frequencies.

Shively Labs is an employee-owned manufacturer of FM broadcast antennas, filters, and related transmission equipment. It has been actively researching and designing products for the HD radio market since 1991.
